Book Magazine
An extensive print and web magazine with a wide array of creative columns.

London Review of Books
Print and web magazine. You get the full version on the web if you subscribe to the print.

New York Review of Books
Thoughtful reviews. Again, this is subscription-based. But you still get a good deal of content as a non-subscriber.

Pages
Great features and recommendations. There's a bit of content for the non-subscribing web viewer, and then they also tell you what's in the magazine, in hopes that you'll pick up a copy.

Readerville
Good reviews and features. They also host discussions. Like the rest, the web component of a print mag.
